The proposed traffic light system (see Fig. 1.2) comprises a metal housing 1 with a terminal block 2 fixedly mounted thereon, at least one protective glass lens 3 (made, for example, in the form of a group lens) of impact-resistant polymer and with placed inside the housing 1 a light source with a given glow color, made in the form of a matrix of LEDs 4 located on the printed circuit board 5, and a power source made in the first embodiment

- 4 versions in the form of a voltage converter 6, and in the second embodiment, in the arhd in the rectifier 7.

At the light source (see Fig. H), the LEDs 4 on the printed circuit board 5 are connected to a pair of connected elements 8, each of which contains at least one LED 4, and each element 8 is connected in series with a corresponding current-carrying (leveling) device 9 determining the currents of the LED (s) 4.

If inside the element 8 two LEDs 4 or more are ikeated, then these LEDs 4 are connected in series.

To ensure reliable operation of the traffic light system on the “1x” railways, a device for matching its operation with the railway automation system (not shown) is introduced into its composition (see Fig. 3,6), connected to the supply line (not shown) through fire relay 10 of the railway automation system.

The matching device with the railway automation system in the first embodiment (see Fig. H) is made in the form of a voltage regulator 6 (acting as a power source and increasing the voltage of the supply line) connected on one side to the fire relay 10 of the railway automation system, and with the other side - to the inputs of the current input devices 9.

With a large number of parallel-connected LED elements 8 in the first embodiment of the traffic light system, a ballast resistor 11 is included in it (see Figure 4), mounted on a metal casing 1, which provides a good heat dissipation to the outside, and is connected in series between the voltage generator 6 and the light source consisting of LED elements 8 and current-sensing devices 9.

With a significant supply line (1 km or more), a traffic light system (in the first version of its execution) is introduced into the structure of the traffic light (see

- 5 Fig. 5) aaaaita device 12 from pickups on the lithium (flare) circuit, made in the form of a first, for example er, dynistor key 13 with a threshold device 14 and connected in series between the power supply converter 6 and the current-setting devices 9.

In the second embodiment of its execution (see Fig. 6}, the matching device with the railway automation system is made in the form of two keys - the second 15 and the third 16, parallel connected by power and sequentially BKJromeHH rat by the signal. When the atom matching device is connected to one the sides to the fire relay 10 of the railway automation system, and on the other hand, to the inputs of the current inputs of the devices 9.

To create the luminous flux of the required shape, the LEDs 4 are located either in the focus of the curved glass lens 3 (see Fig. 7) to obtain a narrow beam used by mast and dwarf railway traffic lights, or out of focus of the protective glass lens 3 (see Fig. 8) to obtain a wider beam used in subway tunnel traffic lights and railway crossing traffic lights.

The proposed traffic light system fuchodion functions as follows.

The first embodiment (see Figs. 1, 3, 4, 5) of a traffic light system is used in dwarf and tunnel traffic lights.

In this system, the current consumed by the light source is significantly less than the current consumption of traffic light systems on incandescent lamps, which were calculated by the railway automation system.

To increase the consumption current, to the value necessary for the reliable operation of the fire relay 10 of the railway automation system, a load transformer 6 is introduced into the traffic light circuit, increasing the supply voltage to the necessary

- 6 quantities, and excessive voltage is extinguished by Focosadaptation devices 9.

With a significant length of the supply licks (3, kk to more) with an induced voltage of less than 70% of the supply voltage, the threshold device 14 of the anti-interference device 12 of the power supply circuit, see Figure 5) does not work and does not bend the first key 13.

In this case, the current through the LEDs 4 does not flow and there is no spurious illumination.

The second version of the traffic light system (see Fir. 2,6), as mentioned above, is used in traffic lights. In this system, when the signal light is turned on (i.e., when voltage is applied through the winding of the fire relay 10 of the railway automation system), the threshold device of the second key 15 is activated and the second key 15 is turned off, the voltage on it becomes less than that necessary for the third key 16 to work The third key 16 does not open.

Power is supplied to the LED elements 8 and the current lamp lights up.

The current consumption of the traffic light system in this case provides a response from the evy relay 10 of the railway automation system and it gives a signal of serviceability of the included traffic light.

If a significant number of LEDs fails, or when a fuse blows, the Fok will be consumed and the fire relay 10 of the railway automation will not work. In this case, the railway automation system generates an alarm.

When the signal light of the traffic light is off, the railway automation system turns on two traffic light systems of the traffic light in series and supplies them with power through the high-resistance winding of the fire relay 10. In this case, the voltage supplied to the LED elements 8 is not enough to ignite their LEDs 4 and signal. 7 outdoor okhun does not burn. In this case, the voltage is not enough to trigger the threshold device of the second switch 15 and the second switch 15 is closed. At the same time, a high voltage is generated at the output of the second key 15, and therefore at the input of the third key 16, the third key 16 is opened and enough current flows through it to fire the relay 10. In this case, the fire relay 10 is activated, and the railway automation system gives a signal about the serviceability of the traffic light supply line.

If the supply line is damaged, the current does not flow through the fire relay 10, and the railway automation system gives an alarm.

Using the proposed utility model allows you to:

1. Significantly increase the efficiency of the traffic light system by increasing the reliability of the traffic light system and reduce the cost of its exploitation.

2. Significantly improve the safety of operation of railways and subway lines.

3. To provide the possibility of replacing obsolete lens sets on incandescent lamps in existing railway traffic light systems with modern traffic light LED heads without any changes to the railway automation control system.

4. To provide the ability to control the health of the power supply circuit of a traffic light system and (or) the health of a traffic light system using the fire relay system adopted on the railway network, regardless of the amount of current consumed by the light source.
